(Universidad de Chile, 2008)En este trabajo evaluamos la estabilidad eductiva de los equilibrios de una clase de modelos económicos compuestos de un continuo de agentes y de un estado agregado del mundo sobre el cual los agentes tienen una influencia ...
-
(Universidad de Chile, 2017)El sistema de producción Mapocho, perteneciente a las empresas del grupo AGUAS, presenta variados problemas: calidad irregular de las aguas afluentes a las plantas, limitaciones en el suministro de agua cruda, problemas ...

(American Meteorological Society, 2020)Raco is the local name given to a strong (gusts up to 17 m s(-1)), warm, and dry down-valley wind observed at the exit of the Maipo River Canyon in central Chile. Its climatology is documented based on eight years of surface ...
-
(IEEE, 2015)Short range radars can provide robust information about their surroundings under atmospheric disturbances, such as dust, rain, and snow, conditions under which most other sensing technologies fail. However, this information ...
-
(Universidad de Chile, 2019)En este trabajo, utilizando técnicas de fluidodinámica, son medidas las amplitudes de ondas de longitud corta en un canal con flujo constante y obstáculos, para así obtener las propiedades de un agujero blanco análogo ...
-
(Universidad de Chile, 2015)El objetivo general del presente trabajo es identificar, analizar y explicar los valores actualmente adoptados por la regulación chilena en relación a intensidades de campo electromagnético y otros parámetros relacionados, ...
-
(Universidad de Chile, 2018)Dentro de los últimos 65 millones de años, el Eoceno Temprano (∼ 56 - 48 millones de años atrás) se caracteriza por ser la época geológica más cálida de la Tierra. Registros paleocli- máticos dan cuenta de temperaturas ...
-
(Springer Heidelberg, 2020)The paper is devoted to the classification of entire solutions to the Cahn–Hilliard equation −u = u −u3 −δ in RN , with particular interest in those solutions whose nodal set is either bounded or contained in a cylinder. ...
-
(2014)The aim of this paper is to study radial symmetry properties for ground state solutions of elliptic equations involving a regional fractional Laplacian, namely (-[delta])[alfa][ro][ípsilon]+u = f(u)in Rn, for [alfa] ...
-
(IOP Publishing, 2017-07-01)We evaluate the astrometric and photometric implications of a series of laboratory tests conducted to study the effects of radiation damage caused by solar protons in space-borne charge coupled devices (CCDs). The photometric ...
-
(IOP Publishing Ltd, 2017)Planets are born in protostellar disks, which are now observed with enough resolution to address questions about internal gas flows. Magnetic forces are possibly drivers of the flows, but ionization state estimates suggest ...
-
(EDP Sciences, 2013)Context. The carbon monoxide (CO) ro-vibrational emission from discs around Herbig Ae stars and T Tauri stars with strong ultraviolet emissions suggests that fluorescence pumping from the ground X1Σ+ to the electronic A1Π ...
-
(Universidad de Chile, 2022)Gracias a los importantes avances tecnológicos, el estudio de los discos protoplanetarios se ha desarrollado rápidamente en las dos últimas décadas. Con instrumentos cada vez mejores, observatorios como ALMA y el VLT han ...
-
(Ariadna Ediciones, 2019)In this paper, we analyse the causes that allowed social movements in 2011 to transform into political parties in Spain and Chile. For this, an in from the premises of radical democracy regarding the construction of the ...
-
(Universidad de Chile, 2023)El estudio de la microf´ısica del polvo c´osmico abarca diversos fen´omenos astrof´ısicos: desde los mecanismos de emisi´on en el medio interestelar, hasta la formaci´on de planetesimales en discos circumestelares. En ...
-
(EDP Sciences, 2018)Aims. With the purpose of investigating the radio emission of new ultracool objects, we carried out a targeted search in the recently discovered system VHS J125601.92-125723.9 (hereafter VHS 1256-1257); this system is ...
-
(American Geophysical Union, 2020)The El Tatio geothermal field in the Chilean Altiplano contains hydrothermal silica sinter deposits overlaying glacial and volcanic units, providing an opportunity to constrain the timing of deglaciation and volcanic ...
-
(Universidad de Chile, 2023)Casi el 30% de las radiografías tomadas en todo el mundo nunca son vistas por un radiólogo cualificado, lo que supone una enorme disminución en la salud de las personas. Este valor aumenta constantemente con el tamaño de ...
-
(Wiley-Liss Inc., 2019)We report the case of a 14 years and 8 months girl, who is the first child of nonconsanguineous parents, with short stature, obstructive hypertrophic cardiomyopathy, multiple facial lentigines, high and wide forehead, ...
-
(Oxford University Press, 2015)A recent reanalysis of archival data has lead several authors to arrive at strikingly different conclusions for a number of planet-hosting candidate stars. In particular, some radial velocities (RVs) measured using Fiber-fed ...
